MACHINE FOR MAKING ROOFING.

Specification of Letters Patent. Patented Oct. 18, 1910.

Application filed January 18, 1910. Serial No. 538,706.

To all whom it may concern:

Be it known that I, HENRY R. WARDELL, a citizen of the United States of America, residing at New York city, borough of Man- 'hattan,-co unty and State of New York, have invented certain new and useful Improvements in Machines for Making Roofing, of which .the following. is a specification.

My invention relates to machines for manufacturing roofing composed of a plurality of lies or webs of flexible fabric such as as stos felt or paper cemented together and comprises means for inserting between the edges of such webs a double thickness of a narrower stri or similar fabric which sha l' have 'no cementing material between its inner faces.

The outer faces of the double thickness strip are'cemented to the webs, and thus the outer edges of the webs are left free and unattached one to the other. They are, in fact, provided with internal, non-adhesive facings. The resulting sheet of roofing has its edges formed of independent leaves which may easily be separated for the purpose of forming an interleaved oint between two. adjacent sections in making a complete roof.

The best form of apparatus embodying my invention at present known. to me is illustrated diagrammatically in the accompanying two sheets of drawing inwhich,

Figure 1 is a longitudinahvertical section in diagram taken on a plane indicated by 1ine'l--l of Fig. 2, and Big. 2 is a detail in perspective of the same mechanism, while, Fig. 3 is a cross section of a sheet of the roofing made in my apparatus.

Throughout the drawings like reference numbers indicate like parts.

land 2 are large rolls revolved by any convenient means (not shown) appllying power to either or both their journa s, 3 and 4. A partition or dam 5 at each end of the rolls (only one being shown in the drawing) forms with the rolls a reservoir into which a suppl of liquid cementitious material 6 (such as iquid asphaltum') is fed cementitious material. These web's may be formed of asbestos felt, or other suitable fabric. Their width is the width of the set of rolls usually about three or four feet.

The action of the apparatus so far deof the same double scribed would be to firmly cement the two webs together, throughout their entire width and so form the usual two-ply roofing. In order to have the ed es of the lies not cemented together an? to leave t em free to separate, I feed in a double thickness of a narrower strip of fabric 14 along and between the edges of the webs 8 and 9. This double thickness strip is referably formed by unwinding a six incli stripof fabric from a roll thereof indicated at 15 on shaft 10, over a guide 11, and down between folding rollers 12, laced 'at'right angles to gu de 11. The i ht 13 of the 'fold comes on the side tower the inside of the webs 8 and 9, and farthest from their edges.

The cementitious material gets between the each web is simply cemented to the outside of one thickness of the narrow strip 14, and

the edge portions of the two webs 8 audit) may be easily separated as shown in Fi 3. f course the number of plies of web ing can be varied, and the number of separating strips could also be varied, but I prefer to use onl one stri at each edge of the webs and fol ed asshown, and inserted between the edges of the webs at each side of tlajhe completed sheet of roofing, as shown in e drawings show only one end of the main rolls, 1, 2 and it should be'understood that the mechanism is duplicated at the other end of the rolls so. as to treat both ed es of-the roofing alike.

aving, therefore, described my invention, Iclaim: 1. The combination with a ppir of rolls, means for maintaining a liquid ody of cementitious material between them and means .forfeeding two webs of flexible fabric between the rolls and through the cementitious material, of mechanism for feed-in a double thickness of a narrower strip of abric between the two first mentioned webs along the ed es thereof.

2. T e combination with a pair of rolls,

means for maintaining a liqxiid body of cemthereof with the bight of the fold on the side entitious material between them and means farthest'from the edges of the webs. for feeding two webs of flexible fabric be- HENRY ARDELL.
